If you're getting delivery, your pizza already comes pre-sliced. But if you're making it at home, when cutting up that pie you'd better make sure everyone gets the same-sized slice lest you start a family feud that could go on for generations. And since nobody wants that, ThinkGeek created this brilliant laser-guided pizza cutter that keeps your slices on target.

Its built-in Class II laser pointer creates an easy to follow bright red line across your pizza, while the three-and-a-half-inch stainless steel blade makes short work of a mountain of toppings or even an extra-thick crust. For $30 it also comes with a built-in flashlight so you can keep on slicing even if the lights go out. Next to pineapple, it could be the best thing to happen to pizza in the past 30 years.
